本標準規(guī)定了壓力傳感器(以下簡稱傳感器)性能的試驗條件、試驗的一般規(guī)定、試驗項目及試驗方法、數(shù)據(jù)計算及處理。本標準適用于壓力傳感器(包括絕壓傳感器、差壓傳感器、表壓傳感器和負壓傳感器)。
除了GB/T 18268.1的要求外,GB/T 18268的本部分更詳細的規(guī)定了下列設備的試驗配置、工作條件和性能判據(jù):低壓配電系統(tǒng)防護設施的試驗、測量或監(jiān)控設備;由電池和(或)被測電路供電的設備;便攜式設備。此類設備包括但不限于GB/T 18216(或IEC 61557)確定的電壓檢測器、萬用表、絕緣電阻測試儀、接地導通電阻測試儀、環(huán)路阻抗測試儀、“剩余電流保護裝置測試儀”(RCD測試儀)和相序測試儀。制造商應規(guī)定設備的預定使用環(huán)境,并從GB/T 18268.1的規(guī)范中選擇適用的試驗等級。
本標準規(guī)定了交流1 100 kV氣體絕緣金屬封閉開關(guān)設備的使用條件、額定值、設計與結(jié)構(gòu)、試驗、選用導則、運輸、儲存、安裝、運行和維護等要求。本標準適用于1 100 kV戶內(nèi)和戶外安裝、頻率為50 Hz的單極封閉SF<下標6>氣體絕緣金屬封閉開關(guān)設備,其絕緣的獲得至少部分通過絕緣氣體而不是處于大氣壓下的空氣。為了便于本標準的使用,術(shù)語“GIS”和“開關(guān)設備”均用于表述“氣體絕緣金屬封閉開關(guān)設備”。本標準涵蓋的氣體絕緣金屬封閉開關(guān)設備是由可以直接連接在一起的各獨立元件構(gòu)成,而且這些元件只能按這種方式運行。根據(jù)需要,本標準對于構(gòu)成GIS的各個獨立元件的相關(guān)標準進行了完善和補充。
本標準規(guī)定了地下水檢測移動實驗室(以下簡稱移動實驗室)的術(shù)語和定義、技術(shù)要求、試驗方法、標志、文件、運輸及貯存。本標準適用于陸地使用的可進行地下水的感官、無機物、有機物、微生物等指標檢測的移動實驗室。

本標準規(guī)定了火力發(fā)電廠熱控系統(tǒng)檢修運行維護的內(nèi)容、方法和技術(shù)管理應達到的標準。本標準適用于火力發(fā)電廠已投產(chǎn)機組熱控系統(tǒng)的檢修和日常運行維護工作。
DIN EN ISO 15970 gives requirements and procedures for the measurement of the properties of natural gas that are used mainly for volume calculation and volume conversion: density at reference and at operating conditions, pressure, temperature and compression factor. Only those methods and instruments are considered that are suitable for field operation under the conditions of natural gas transmission and distribution, installed either in-line or on-line, and that do not involve the determination of the gas composition. This International Standard gives examples for currently used instruments that are available commercially and of interest to the natural gas industry.
This British Standard gives recommendations for, and guidance on,the design for the installation of instrumentation of measurementand control systems in the process industry, and the implementationand commissioning of this installation. It is intended to be used asa manual of good practice on the site and also to assist those whodesign the installation.
This European Standard describes a hot-wire (parallel) method for the determination of thermal conductivity ofrefractory products and materials. It is applicable to dense and insulating shaped products and to powdered orgranular materials (see 6.2), for thermal conductivities of less than 25 W/m.K. The limits are imposed by thethermal diffusivity of the test material and therefore by the dimensions of the test pieces; higher thermalconductivities can be measured if larger pieces are used. Electrically conducting materials cannot bemeasured.NOTE 1 The thermal conductivity of products with a hydraulic or chemical bond can be affected by the appreciableamount of water that is retained after hardening or setting and is released on firing. These materials may therefore requirepre-treatment; the nature and extent of such pre-treatment and the period for which the test piece is held at themeasurement temperature as a preliminary to carrying out the test, are details that are outside the scope of this standardand should be agreed between the parties concerned.NOTE 2 In general it is difficult to make measurements on anisotropic materials and the use of this method for suchmaterials should also be agreed between the parties concerned.
